Welp, Looks like I jumped the gun and I am glad I did some digging with the roomates. Turns out the landlord's boyfriend assumed it was my oktoberfest (worst beer I ever brewed but that id a story for another day) that I had left in the kitchen for everybody to enjoy. So I am trading them and entire case of my oktoberfest for the bottles back
I also have the last 6 pack of my pale ale and a six pack of applewine ready to give to the contractors to clear my conscience from suspecting them!
I am glad this spurred some debate so feel free to carry it on in a hypothetical sense!
